I just tried the update of my 4 days old Helix to 2.01.0 : after an hour and seeing strange Japanese symbols on the screen I began to read some posts on this forum about update problems. Seemed like almost everybody here faced minor or major issues and I started to freak out since it's not my first bad encounter with updating electronic hardware through the internet.
So I shut the Helix down and back on : I got the message "update failed (or sort of) and the feared orange "0" in the left upper corner.
After a few deep breaths I just shut down my laptop (mac running El Capitan), turning it back on and trying it again (still using the latest version of the editor (and updater) of course).... and to my surprise it worked (rebuilding presets by helix took another 3-4 minutes)!!
So keep the spirits up, stay calm and perform the update right after you've started your computer without doing anything else - pray - and it might just work.
I'm posting this because I know how frustrating it can be to have such expensive devices not doing what they are supposed to do right away.
and now I'm going to explore this monster machine !
